Well Records kinda confuses me, doing nslookup type PTR on my IP i get the following result:
4x.1xx.2xx.21x.in-addr.arpa name = xxxxxx-srv01.netvisao.pt.
Even though i've read some articles on it, it still don't get records that well, cause by the above it tells me I have one set that my ISP gave me right? Do i need to insert it somewhere on my server? Like on the dns records of every domain? How does that work. Sorry for all those questions.
Thanks a lot.
